How Your Choices May Affect the Results

Genders

Gender influences Basal Metabolic Rate (BMR) mainly because men and women tend to have different body compositions, even at the same weight. Since muscle burns more energy than fat, people with more muscle mass—like men, who generally have a higher lean muscle percentage—usually have a higher BMR.

  • Hormonal Differences: Higher testosterone levels in men promote muscle growth, while higher oestrogen levels in women tend to increase fat storage.
  • Body Composition: Men generally have more muscle mass, boosting their metabolic rate.
  • Organ Size: Differences in organ sizes between genders also play a role.

Weight

Weight affects BMR because larger bodies need more energy to keep things running, even at rest.

  • More Mass, More Energy: Higher weight typically means a higher BMR.
  • Muscle vs. Fat: Muscle burns more calories than fat, boosting BMR.
  • Organ Load: Higher weight means organs work harder, increasing energy use.

BMR Calculation Choice

The BMR calculation method you pick can change your result since each formula estimates your metabolic rate differently.

  • Harris-Benedict Equation: A classic formula that may underestimate BMR for muscular individuals.
  • Mifflin-St Jeor Equation: More accurate for modern body types, using weight, height, and gender.

Diet Type

Your diet type, including options like vegan or vegetarian, can impact your BMR.

  • High-Protein Diets: Preserve muscle mass, keeping BMR high.
  • Low-Carb Diets: May lead to weight loss but risk muscle loss if not balanced.
  • Vegan/Vegetarian: Focus on nutrient-dense, protein-rich foods to maintain muscle mass.

Activity Level

Staying active boosts BMR by building muscle and increasing calorie burn.

  • More Muscle, More Burn: Strength training raises BMR.
  • The Afterburn Effect: Intense workouts increase post-workout calorie burn.

Height

Taller people generally have higher BMRs due to their larger surface area, muscle, and organ size.

Diet Goal

Your diet goal can shape your BMR by influencing body composition.

  • Weight Loss: Caloric deficits can lower BMR due to muscle loss.
  • Muscle Gain: Eating in surplus with strength training boosts BMR over time.

Health Conditions

Health conditions like thyroid disorders, diabetes, and chronic illnesses can influence your BMR by affecting how your body processes energy.
